'SHIP' S 'LIGHT Filed May 10, 1930 2 Sheets-Sheet 2 Patented May 17, 1932 STATES PATENT erre- SHIPS LIGHT Application filed May 10, 1930, Serial No. 451,367, and in Great Britain May 13, 1929.

This invention relates to ships lights and has more particular reference to those known as pivoted lights in which a glass holder is pivotally mounted within the main frame that is secured to the ships hull or other part so that it can be angularly moved about a diametrical or medial axis to open the glass holder to any desired extent. In such pivoted lights, the glass holder which is usually of circular shape is provided with diametrically opposite pins or projections that fit in slots in the inner wall of a double walled or boxlike frame or body so that it is capable of being slidably or axially moved away from the seating against which it bears when closed, into a position where it is free to be angularly moved about the aXis passing through the pins or projections.

A ships light of the type or character referred to is shown in Letters Patent No. 589,315, and among the objects of the present invention may be noted that of providing a construction which will be free from certain objections that experience with the construction of such patent has shown to be incident thereto.

The object of the present invention is to provide an improved construction of this type of light that avoids the use of the afore- 80 said double walled or boxlike frame, which apart from being somewhat expensive to manufacture is open to the objection that it forms a space or receptacle in which water or foreign matter entering through the said slots can collect or accumulate. The improved construction in addition to avoiding the'objection above referred to, provides a more satisfactory bearing for the glass holder within the main frame or body so as to facilitate the sliding and angular movements, whilst it also'has the' advantage that it is less expensive to manufacture.

According to this invention the main frame or body is so constructed that it comprises a single wall which is provided with grooves or channels in its inner surface to receive trun nions or projections on the glassholder. The grooves or channels are shallow and comparatively wide and the said trunnions or projections which fit closely therein, are flat at their ends and bear on the flat inner surfaces or bottoms of the said grooves or channels to provlde a substantial bearing which facili- 'tates the sliding or axial movement of the glass holder, and also the angular movement. Further according to this invention the construction is suchthat the glass holder can be readily inserted in or removed from the main frame at the inboard side of the frame. The main frame is provided With an internal flange or rim having a rubber seating against which an annular projection or the like on the glass holder is pressed to make a Watertight closure, portions of this flange or rim adjacent to the inboard ends of the aforesaid grooves being cut away to provide openings which are normally covered by detachable plates or strips each having a projection with a rubber seating that forms a continuation of the seating in the flange or rim on the frame. By placing the glass holder in a position with its axis at right angles to that of the main frame, it can be inserted in the said openings so that its trunnions pass into the said grooves in the main frame, whereupon it can be angularly displaced about the vertical axis passing through the trunnions, so that it can bebrought into engagement with the rubber seating. The detachable plates or strips when fitted, complete the said flange and rubber seating and secure the glass holder within the groove. In some cases the glass holder may be inserted in or removed from the main frame at the outboardside, for which purpose'abutments or an abutment ring may be provided adjacent to the outboard ends of the said grooves. The grooves however may be so shaped at the outboard end as to limit the outward movement of the trunnions on s the glassholder. 90 In order that the said invention may be clearly understood and readily carried into effect, the same will now be described more fully with reference to the accompanying drawings, in which Figure 1 is a front View of the inboard side of aships light according to the present invention.

Figures 7 to 13 are detail views hereinafter referred to.

A represents the main frame or body which as shown is constituted by a single wall or ring having a flange A that is adapted to be secured to the ships side or other part in any suitable or usual manner. Strengthening webs A extend from the said flange to the inner or inboard end of the single walled frame A where a flange or rim A is provided, this rim being provided with a rubber seating A as shown more particularly in the sectional views. B represents the glass holder in which the glass plate B" is held in any suitable or usual manner, the inboard side of the glass holder having an annular projection 2 which can be forced against the rubber seating A in the rim A by means of swing bolts C on the glass holder engaging with pivoted lugs C on the main frame as shown in Figures 1 and 2. Raised portions are provided at diametrically opposite parts of the inner surface of the main frame A, and they are formed with shallow and comparatively widegrooves or channels A that extend from the inboard side of the frame A to the outboard side. The glass holder B is provided with diametrically opposite trunnions or circular projections 13 which are of such diameter as to fit closely in the said grooves A to provide a sliding fit without any lateral movement, whilst the outer ends of the said trunnions or projections are flat so as to rest or bear against the fiat inner surfaces or bot-- toms of the grooves. In order to open the light, the glass holder B is slidably moved in an axial direction from the position shown in Figures 1, 2 and 6 towards the outboard side of the glass holder, and upon the trunnions B reaching the outboard end of the grooves A, the glass holder can be angularly isplaced about the axis of the trunnions to assume a position at right angles to the main frame as shown in Figure 3. The bearing afforded by the trunnions or projections B within the said grooves A enables the sliding or axial movement of the .glass holder away from or towards the seating A to be easily effected, and it also facilitates the angular movement of the .glass holder .aboutthe vertical axis passing through the aforesaid trunnions. The glass holder can be inserted in the frame at either the inboard side or the outboard side of the frame as both ends of the grooves A are normally open. Detachable stops or an abutment ring A are provided at the outboard ends of the grooves as shown in Figures 2, 4and 5 to close the latter and thus prevent unrequired removal of the glass holder at this side. The said grooves may however be shaped as shown in Figure 9 so as to limit the outward movement of the trunnions and thus prevent withdrawal of the glass holder at the outboard side. In order to enable the glass holder to be inserted or removed at the inboard side, the rim A of the frame A carrying the rubber seating A is provided with openings A (see Figures 8, 9 and 10) adjacent to the ends of the grooves A. These openings may be closed by means of plates D which can be secured to the face of the rim A by screws or other means, and are provided with projections D that lit closely within the said openings A to complete the annular formation of the rim A The said projections D are also provided with a. portion of rubber D or the like that forms a continuation of the rubber seating A in the rim A When the said plates D with the projections D containing the rubber strips D are removed, the glass holder, when placed in a position so that its axis is at right angles to the axis of the main frame can be withdrawn or inserted as the width of the openings are such as to permit of the glass holder passing through them. After the glass holder has been inserted so that the trunnions lit in the said moves, it can be swung on the vertical axis passing through the trunnions into the position shown in Figures 1, 2 and 6, and the plates D can be replaced so that the openings A are closed. The rubber seating for the glass holder is therefore completed and the latter can be moved or drawn against the said seating by the bolts C to provide a water-tight closure. For the purpose of retaining the glass holder in the fully open position pivoted retaining pieces E are provided on the main frame so that they can be placed in a position to engage with the front and rear surfaces of the glass holder as shown in Figure 3. These retaining pieces E in the example shown are carried on the detachable plate or strip D that closes the opening in the rim A adjacent to the lower groove A and this plate or strip may also carry a pivoted catch piece F which is adapted to engage with a notched or slotted projection 13 on the inboard side of the glass holder so as to retain the latter in a fixed position a short distance away from the seating A to provide a small opening for ventilating purposes. If desired, an additional catch may be provided to retain the glass holder in any desired angular position. A cover or deadlight may be fitted to the glass holder on the outboard side if required.

The subject matter of the present improve ments differs from that of the earlier patent before referred to in that the grooves or guideways for the glass holder trunnions are formed entirely within the main frame, and

such channels or grooves are of substantially uniform width throughout the depth.

According to the earlier, patented, construction, the guides for the glass holder trunnions or pivot pins were extended outward from the main frame and were permanently closed at their outer ends. Also, such channels or grooves were of greater width at the portions remote from the glass holder and the pivot pins or trunnions were provided with enlarged end portions which were received in such expanded portions of the grooves.

Experience with the arrangement shown in the patent has shown that said undercut grooves, closed at the outer end, are easily clogged by sand or other material accumulating therein which interferes with the desired free movement of the trunnions and glass holder.

By forming the trunnion or pivot pin guides between two raised port-ions or ribs on the inner surface of the frame and making such pins or trunnions of substantially uniform diameter throughout their length, this objection is avoided.
